Force Balance of Particles in Water During Ultrafiltration Membrane Process

Abstract Membrane filtration is vital in our daily lives to extract fresh water from contaminated water. However, membrane suffering fouling, which induced by accumulations of particles on surface. Due the hydraulic field and electrical (from functional groups membranes) near surface, particle will be exerted different forces. The intermolecular forces such as Lateral lift force, Brownian shear-induced Van Der Waal force electrostatic repulsion may affect fouling process, flux inside system cab exert permeance drag surface membrane. In order figure out that a model was established about process. model, velocities each are listed calculated this paper. From analysis, relations between velocities, represents efficiency, forces, or shear well illustrated. This article shows importance potentially understanding process providing insight mitigation for
